// Test program for SetPos(), DispOut(), ?, and ??  Clipper compatibility
// The results should be identical between Harbour with the GT API and
// Clipper. Inkey() is used to pause the display at certain points to make
// it easier to compare scrolling compatibility. A Tone() is sounded before
// each Inkey(0) call.
